Wax and varnish removal from gasoline?

[phord]

What will happen if I remove wax and varnish from gasoline?

[thatguitarguy]

What?? The world will end?? I give up. Please tell me...

I'm no chemist, so help me out here.
Where in the chemicals that make up gasoline is the "wax and varnish?"

Material Safety Data Sheet.

I did find this dealing with heavy lubricants used in oil production equipment:

"Guardex Stuffing Box Oil is a specially formulated lubricant, designed as
a rod and packing lubricant for both centrifugal and reciprocation action
pumps and equipment. The additives in Guardex Stuffing Box Oil breaks
down and controls wax and varnish build-up, while providing a superior
film of lubricant on the rod surface. Guardex Stuffing Box Oil lubricates and
prolongs the service period of packing and seals, while anti-corrosion
additives help combat environmental corrosion such as H2S or salt water.

"Recommended Uses
Guardex Stuffing Box Oil is recommended for use in all drip oilers or tank oil
systems, for lubrication of pump rods and packing.

"Advantages
*Superior lubrication
*Eliminates wax and varnish build-up on rods
*Extends packing life
*Equally effective on reciprocating and centrifugal rods
*Combats corrosion (eg. H2S, salt water, etc.)
*Extend life of equipment

Guardex

I'm not seeing a connection with gasoline.

Old gas leaves gook commonly referred to as gum and/or varnish. Not sure about "wax" but whatever.

I've just been dealing with that exact issue. I'm resurrecting a freekin' Gold Wing which has been sitting for many, many years (10?) but not pickled for storage. #4 carb needle was stuck open, dumping much raw fuel into intake and some made it to crankcase too I'm sure. Yeah, motorcycle carbs... I only wanted to drop the float bowls and examine floats and needles BUT NO, the manual says disassemble the entire motorcycle to get those bowls off cuz the carbs are all siamesed together! To **** with that, with the ingenuity of MacGyver and the skill of a surgeon, I removed the worst offender's bowl, swiped a mirror off the x-girlfriend's makeup compact, and got er done with no other disassembly. Oh... right... the point of the post. Lots of gum and varnish kept the needle from moving up and down in the seat. Had to physically scrape it off (knife, scotchpad) and chemically clean the rest of the residue with carb cleaner. Sparkplugs told me the right bank was OK, so that left #2 as "doubtful". Got some gas additive "carb cleaner" and let her have a super concentrated shot of it.

3rd day now and it's running fine!

Old gasoline --> wax/gum and varnish

So, taking out the "wax and varnish" means taking the gas out of gasoline.

Not sure a car can run on "oline" only.

I'm designing a filter guaranteed to remove the wax from gasoline, but it's going to be expensive. I can also make it to remove varnish, but that will cost extra. PM me your credit card number...

I'm still jealous of wherever you are since you aren't here in MN enjoying the sub zero temps. Although yesterday was a heatwave reaching 20°F I took the girls out sledding, lol. When you coming back?

Phord: Are you talking about older gas or new gas?

I use alcohol. But don't forget to change your fuel filter.

As a lifelong MNer with around 50 years of MN winters under my belt (many of them the EXTRA brutal NW corner variety) I have finally woken up to the joys of being a snowbird. In spite of my joyous proclamations about how great longer, colder, darker MN winters are... the truth is, I think they suck. I am sampling the Central California coast. Very pretty, practically the same mild weather every day year around, but real estate is 10x the cost vs back in the sticks. MN budget with Cali expenses = whoops, good thing you don't get too cold in a cardboard box under a bridge here. I planned to come back in April but my (now) ex-GF has been hatin' on me ever since I stepped off the plane... so I could end up homeless prior to my return flight. Too bad I can't ride that Wing back through 3 feet of snow.

I read that the burning wax and varnish are the major source of pollution and that is the ethanol is the added to help them burn properly, and distilled gasoline should be clear colored (not yellowish) and the filter is easy to make (big fuel filter filled with coconut charcoal powder and activated charcoal powder) . So if the filter works there will be no deposits in engine and the oil lasts longer interwals and this results in the longer engine life right?
